Patent CA-2129283-A1 (CA)
Inventor: BRIGGS EUGENE C
IPC: F24H3/06
Filed: 1994-08-02
Abstract: A furnace including an elongated housing having an air intake adjacent one end of the housing and an air discharge vent adjacent the other  end of  the housing utilizes a substantially U-shaped heat exchanger positioned within the housing and a partition supported within the housing so as to separate the interior of the housing into first and second zones.  One leg section of the U of the heat exchanger is positioned within the first zone of the housing, while the other leg section of the U is positioned within the second zone of the housing.  A fuel burner assembly directs a flame and attending combustion products into one leg section of the heat exchanger so that the heat generated by the flame and combustion products are absorbed through the inside surfaces of both leg sections.   The furnace also includes a fan for forcing room air into the housing through the air intake so that a fraction of the air moves through the first zone and absorbs heat from the outer surfaces of the one leg section and so that a remainder of the air moves through the second zone and absorbs heat from the outer surfaces of the other leg section.   The partition provides a first opening and a second opening through which the first and second zones communicate with one another wherein the first opening is disposed adjacent the air intake end of the housing and the second opening is disposed adjacent the discharge vent end of the housing.  The remainder of the air is permitted to mix with the fraction of the air through the second opening before exiting the housing means through the discharge vent with the fraction of the air.

Patent CA-2134402-A1 (CA)
Title: Zero lead planer
Inventor: CROGHAN CHARLES L
IPC: B23D5/00
Filed: 1994-10-26
Abstract: A planer is improved by recognizing the source of instability of a board relative to a guidebar. An angled relationship between feed roller force the guidebar and holds the board against the guidebar. Traditional cutting heads urging the board in the opposite direction relative to that of the feed rollers, develop lateral force vectors kicking the board away from the guidebar. By establishing a zero lead relationship between the cutter heads and the board as it rests against the guidebar, the board enjoys greater stability. The disclosed apparatus further includes an air regulated top pressure plate establishing a given separation between itself and a cutter head, but accommodating abnormal operating conditions, i.e., jammed boards, by vertical movement relative to the cutter head facilitates remote actuation to quickly relieve a jammed condition. Also shown, a bearing housing for a cutter head support shaft is carried on an articulated hinge to improve manual mounting of the bearing housing upon the shaft.

Title: Energy-Efficient Fire Door
Inventor: BARGEN THEODORE J
IPC: E06B5/16
Filed: 1994-11-15
Abstract: An energy-efficient, wood-skinned fire door having a laminate construction.  There is a core panel formed of a fire-resistant material, preferably mineral fiber board.  The perimeter frame around this has a channel formed in its inner edge for receiving the core panel in a close interfit therewith.  This supports the panel in the channel, and also eliminates any direct path for a fire to proceed past the edge of the fire-resistant panel.  Foil-covered thermal insulation panels are positioned on opposite sides of the core panel, and these are covered with wooden door skins.  This provides a structure which is highly fire resistant and exhibits excellent insulation qualities, yet which is also aesthetically pleasing so as to be suitable for residential use.

Title: Methods of single nucleotide primer extension to detect specific alleles and kits therefor
Inventor: EYAL NURIT
IPC: C12Q1/68
Filed: 1993-07-01
Abstract: A method of determining the identity of a nucleotide base at a specific position in a nucleic acid of interest is described. The identity of the nucleotide is based on whether or not a primer is extendable in the presence of a specific substrate nucleotide.  The nucleotide base to be determined lies at the 3' end immediately adjacent to the 3' end nucleotide of the primer. The primer would be extended if the substrate nucleotide is complementary to the nucleotide base in the nucleic acid of interest, and it would not if there is no said complementarity. The method used to determine a normal and mutated gene is illustrated in the figure.

Title: Valved prn adapter for infusion devices
Inventor: PURDY E ROBERT
IPC: A61M39/00
Filed: 1995-08-02
Abstract: A valved adapter for a medical access device includes a body with a longitudinal axis. The body has a proximal first end, a distal second end and a passageway therethrough which has an inside surface. The passageway has a chamber defined by a proximal shoulder and a segmented distal shoulder both projecting inwardly from the surface of the passageway. The chamber is located intermediate the first end and second end of the body. The adapter includes a valve contained within the chamber for selectively obstructing and allowing fluid flow through the passageway. The valve includes an elongate resilient member with an axis substantially coaxial to the longitudinal axis of the body having a proximal end and a distal end. The elongate resilient member is axially compressed between the distal shoulder and the proximal shoulder, the compression biasing the valve to a normally closed position. The proximal end of the resilient member forms a substantially fluid tight seal with the proximal shoulder which obstructs fluid flow through the passageway. The adapter further includes a pusher for selectively further axially compressing the resilient member so that the proximal end of the adapter no longer forms a fluid tight seal with the proximal shoulder thereby allowing fluid flow through the passageway. The adapter includes fittings for attaching the adapter to a medical access device and for attaching fluid delivery devices to the adapter.
